ICE3A2065Z 개요
An SMPS current-mode controller with integrated MOSFET is a category of power-supply IC that combines the control loop, gate driver, and high-voltage power switch in a single die. The current-mode architecture regulates the output by sensing peak primary current and comparing it to an error-amplifier-derived threshold on every switching cycle. By integrating the 650V MOSFET and startup cell, the CoolSET-F3 family reduces external component count, simplifies PCB layout, and improves reliability compared with discrete PWM-controller-plus-MOSFET designs.
Key specifications include a VCC supply range of 8.5 V to 21 V, quiescent current of 7.1 mA, maximum drain current of 2.0 A pulsed, junction temperature range of -25 °C to 130 °C, and thermal resistance (RthJA) of 96 K/W. The integrated 650V CoolMOS withstands typical 85-265 VAC universal-input offline rectified rails with substantial derating margin. A Current Sense (CS) pin provides cycle-by-cycle peak-current limiting, while the internal current-mode PWM comparator generates the duty cycle from the CS signal and the internal reference ramp.
Typical applications include low-power AC-DC adapters (sub-30 W), auxiliary standby supplies in white goods and appliances, DVD/STB standby rails, and low-power LED driver front ends. The wide 85-265 VAC input range and Active Burst Mode make it suitable for designs seeking ENERGY STAR or EuP Tier-2 standby compliance without an additional burst-mode controller IC.
When designing with the ICE3A2065Z, size the CS sense resistor for peak primary current at minimum VIN, account for the 96 K/W thermal resistance when laying out PCB copper area, and ensure the VCC hold-up capacitor covers the IC's start-up sequencing before auxiliary winding takes over. Note that the part has reached end-of-life for new designs; Infineon recommends the ICE3A2065ELJ as the active replacement (different pinout and package - PCB rework required).

일반적인 애플리케이션
ICE3A2065Z 적합 용도: 6 애플리케이션s: Universal-Input AC-DC Adapter (sub-30 W), White Goods Auxiliary / Standby Supply, Set-Top Box / DVD Player Standby Rail, Low-Power LED Driver Front End, Industrial Auxiliary Supply (24 V / 12 V Rails), Printer / Copier Low-Voltage Logic Supply.
Universal-Input AC-DC Adapter (sub-30 W)
The ICE3A2065Z is purpose-built for universal-input (85-265 VAC) flyback adapters up to 28 W output. Its integrated 650V Depletion CoolMOS handles the rectified 375 VDC bus with substantial margin, and the 100 kHz fixed switching frequency simplifies transformer design for 5-28 W charger and wall-wart applications. Active Burst Mode keeps standby below 100 mW - critical for ENERGY STAR and EuP Tier-2 compliance on consumer adapters. Designers place CS resistor on the source return, VCC hold-up cap on pin 3, and a TL431 + opto-coupler feedback network into pin 6 (FB). Compared to discrete PWM-controller + external MOSFET designs, the integrated approach reduces BOM by 8-12 parts and improves reliability.

White Goods Auxiliary / Standby Supply
In washing machines, refrigerators, and dishwashers, the ICE3A2065Z powers 5-15 W auxiliary rails (display, control MCU, sensors) from the rectified mains. Its 650V integrated startup cell eliminates the high-voltage startup resistor chain that fails in field - a known reliability improvement for white-goods. The 96 K/W RthJA permits simple PCB copper heatsinking in confined appliance enclosures. Active Burst Mode keeps standby below 100 mW for EuP Tier-2 compliance, even at <1 W continuous load. Designers typically choose 100 kHz to keep transformer size compact while staying below EMI limits without complex filtering.

Set-Top Box / DVD Player Standby Rail
The ICE3A2065Z is widely deployed in STB and DVD standby supplies where <100 mW standby power is required by ENERGY STAR and EU regulation 1275/2008. Active Burst Mode cycles the MOSFET on/off at light load, reducing switching losses while maintaining output regulation. The integrated 650V MOSFET and startup cell reduce BOM cost by ~$0.15 vs discrete approaches. The 7-pin PG-DIP-7-1 through-hole package is preferred for hand-soldered service-friendly repair in consumer electronics. Designers use the 100 kHz fixed frequency for predictable EMI filter design and synchronization with downstream DC-DC converters.

Low-Power LED Driver Front End
For sub-25 W isolated LED drivers, the ICE3A2065Z serves as the PFC-front-end AC-DC converter feeding a downstream buck or constant-current stage. The 650V breakdown handles 230 VAC rectified mains directly with adequate derating, and the 1.05 ohm RDS(on) limits conduction loss at 15-20 W continuous output. Current-mode control simplifies the loop compensation for an isolated flyback feeding a constant-current load. Active Burst Mode supports dimming-to-off standby states required by modern smart-lighting regulations. The PG-DIP-7-1 package suits through-hole driver housings common in linear-LED luminaires.

Industrial Auxiliary Supply (24 V / 12 V Rails)
In industrial PLCs, sensor hubs, and machine controllers, the ICE3A2065Z generates isolated 24 V or 12 V rails from 85-265 VAC mains for relay coils, op-amp signal conditioning, and MCU power. The 650V integrated MOSFET simplifies surge-withstand (EN 61000-4-5) by eliminating the external startup-MOSFET failure point. Junction temperature range of -25 °C to +130 °C covers most industrial enclosures. The 100 kHz fixed frequency avoids interference with industrial communication bands (e.g., 100 kHz is well below typical 100 kHz-30 MHz PLC carrier ranges when properly filtered).
추천
Printer / Copier Low-Voltage Logic Supply
Office printers and copiers use multiple low-voltage DC rails for control logic, stepper motors, and displays; the ICE3A2065Z provides the main 24 V or 12 V isolated rail in sub-25 W sections. Its compact PG-DIP-7-1 footprint and integrated 650V switch reduce board area vs discrete PWM solutions. Active Burst Mode keeps standby below ENERGY STAR requirements when the printer is idle. Designers appreciate the 100 kHz fixed frequency for predictable EMI filter design in noise-sensitive office environments, and the device's mature field-deployment history in this application.

설계 노트
Estimated: at VIN = 325 VDC (230 VAC rectified) and a 15 W output, the integrated CoolMOS dissipates approximately (1.5 W conduction + 0.4 W switching) ≈ 1.9 W. The PG-DIP-7-1 package's RthJA of 96 K/W produces a junction temperature rise of roughly 180 °C above 25 °C ambient - well above the 130 °C rating. Reduce VIN to 85-132 VAC designs OR attach the tab to ≥ 100 mm² of copper on the drain-plane side. Always size the primary clamp (RCD snubber) for the worst-case 265 VAC rectified peak plus 50 V leakage spike margin.
The 96 K/W RthJA of PG-DIP-7-1 assumes a minimum copper pad on a single-sided 1 oz board. For continuous 28W full-power operation, place the IC's drain tab (pin 7) on at least 150 mm² of 2 oz copper to drop RthJA below 70 K/W. Keep the CS sense resistor trace short and direct to GND (pin 1) - long CS traces inject noise into the current-mode loop and cause subharmonic jitter at duty cycles > 50 %. Add a 100 nF ceramic bypass on VCC (pin 3) within 3 mm of the pin.
Do not load the VCC pin above 21 V absolute maximum - exceeding this destroys the internal regulator. Always verify the auxiliary winding turns ratio so VCC settles between 12 V and 18 V under nominal load. Do not operate the FB pin (pin 6) above the internal 5 V clamp or below -0.3 V; add a 10 kohm series resistor for opto-isolator isolation. Do not skip the soft-start capacitor on the CS pin - without it, transformer saturation on hot-insert events can rupture the CoolMOS. Finally, do not use the ICE3A2065Z in new designs - Infineon has NRNDesignated it; specify the ICE3A2065ELJ instead.
Keep the high-voltage drain loop (rectifier bridge + transformer primary + CoolMOS drain) area to a minimum - this is the primary EMI-radiating loop at 100 kHz and harmonics. Place Y-capacitors from primary GND to secondary GND close to the transformer; the ICE3A2065Z is designed for EN 55022 class-B compliance with proper layout. Maintain > 6 mm creepage between the drain (pin 7) and any low-voltage pin (CS, FB, VCC) per IEC 60950 reinforced-insulation requirements. Star-ground pin 1 separately from the CS-resistor ground return.
